One of the features we rely on is the "Text Tool" component in Adobe Illustrator.

Last week for no explainable reason (There were no event codes in any event log - system, application, etc) Adobe Acrobat Professional stopped working (i.e. would not open any pdf documents)

After we re-installed Adobe CS 6.0 (Above applications were chosen) we were unable to open Adobe Acrobat Professional and now the "Text Tool" component in Adobe Illustrator will not work. When it's selected, there is nothing displayed on the Illustrator document to indicate text entry.
